BUSCH-JAEGER BJ 1515 U-12-101 Alarm Signalling Insert for Potential-Free Contacts 2CKA001582A0428

This alarm signalling insert provides a reliable interface between potential-free security contacts and a central alarm system. It accepts signals from door/window contacts or motion detectors and forwards them via a single changeover relay, making it a flexible building block for custom security setups.

Highlights

• Potential-free changeover contact (SPDT) for universal integration
• Switching capacity up to 24 V AC/DC, 1 A
• Flush-mounted design compatible with major Busch-Jaeger switch ranges
• Passive operation – no internal power supply required

In daily use

The insert sits discreetly behind a compatible cover frame and connects directly to screw terminals. It works with standard alarm loops and can be used in residential or commercial security installations. Because it requires no auxiliary power, it remains functional even during mains failure when used with battery-backed alarm panels.
